This should be further up. The title is definitely wrong and misleading. "Improving my shortest path algorithm with Dijkstra's algorithm by a factor of 2700!" would be more accurate. The author is an undergraduate student so probably just missed that part about Dijkstra's algorithm, but the title should be changed nonetheless.
